What I claim as my invention is:

, 1. A vibration damper for aerial cables comprising a casing; a rack slidably guided in the casing and adapted for connection at right angles to a cable; a spindle journalled in the casing; a speed multiplying gear train between the rack and the spindle adapted to cause the spindle to rotate in one direction or the other according to the direction of motion of the rack relative to the casing; and means yieldingly resisting the setting in motion of the spindle ineither direction comprising governor fly balls rotated by and about the spindle in one direction or the other fall Within the scope of according to the direction of motion ofthe spindie.

2. A vibration damper for aerial cables corn'- prising a Weighted casing; spring suspension means connected With the casing and adapted for connection with a cable; a gear train mounted on the casing; an actuating member for the gear train adapted for connection at right angles to a cable; a spindle journalled in the casing, the gear train being adapted to cause the spindle to rotate in one direction or the other according to the direction of motion of the actuating member relative to the casing; and inertia means yieldingly resisting the setting in motion of the spindie.

3. A vibration damper for aerial cables comprising a Weighted casing; spring suspension means connected with the casing and adapted for connection with a cable; a gear train mounted on the casing; an actuating member for the gear train adapted for connectlon at right angles to a cable; a spindle journalled in the casing, the gear train being adapted to cause the spindle to rotate in one direction or the other according to the direction of motion of the actuating member relative to the casing; and inertia means yieldingly resisting the setting in motion oi the spindle in either direction.

4. A vibration damper for aerial cables comprising a Weighted casing; spring suspension means connected with the casing and adapted lior connection With a cable; a gear train mounted on the casing; an actuating memer for the gear train adapted for connection at right angles to a cable; a spindle journalled in the casing, the gear train being adapted to cause the spindle to rotate in one direction or the other according to the direction of motion of the actuating member relative to the casing; and inertia means yieldingly resisting the setting in motion of the spindle in either direction comprising governor fiy balls rotated by and about the spindle in one direction or the other according to the direction of motion of the spindle. v
